Abstract

CAS (Conditional Access System) is a content protection solution that restricts access to the system according to user`s standing and only authorized users can access the content in a pay-TV system. DCAS (Downloadable Conditional Access System) can download CAS client which is a software implemented via network. In recent years, research and development has been carried out on DCAS to solve the problems of compatibility among heterogeneous devices and internetworking with other services. In this paper, we propose key generation and management scheme for efficient interoperability among different DCASs based on PBC (Pairing Based Cryptography).
